PERMANENT MAGNET GENERATOR

摘要

A new configuration for a double-sided rotor, radial flux, air-cored, permanent magnet electric generator (1) is disclosed. The generator (1) includes two radially spaced apart rotor portions (33, 35) defining an air gap between them and each having a plurality of alternating polarity permanent magnets (41) arranged on their inner surfaces, mounted for rotation in the air gap. A modular stator (43) is positioned in the air gap and includes a base (45) having attachment formations (60) spaced apart about its surface and a plurality of individually moulded, polymeric resin stator modules (53). Each stator module (53) has complementary attachment formations (59) for attachment to the base (45) and includes at least one non-overlapping compact wound coil (61) which is embedded within the resin.
